According to a new study nuts are the latest healthful substance that can improve cholesterol and other blood lipid levels in the blood.
Researchers claim that eating nuts can ward off heart attack risks as nuts contain good fats, fiber, and antioxidants.
In a pooled analysis of 25 intervention trials conducted by Dr. Joan Sabaté of Loma Linda University in California and his colleagues the findings confirm that with an average intake of 67 grams of nuts a day, the total cholesterol was reduced by 5.9%. They further noted that the bad cholesterol was reduced by 7.4%.
To gauge the effects of nut consumption, a pooled analysis of raw data from 25 intervention trials was conducted in seven countries that included 583 men and women with various blood lipid problems. The sample size ranged from 10 to 49 years.
The study was conducted on people who were not taking lipid-lowering medications. The dietary interventions whose duration ranged from three to eight weeks contained exclusively nuts like almonds, hazelnuts, pecans, pistachios, walnuts, peanuts, and some pine nuts. The quantities ranged from 23 to 132 grams per day, with a mean of 67 grams.
The interventions on the sample reflected the total cholesterol at 5.1%, LDL cholesterol at 7.4%. Further, the ratio of LDL to HDL cholesterol was 8.3%, followed by ratio of total to HDL cholesterol to 5.6%.
Summing the results of the study Sabaté and his colleagues wrote,' that greater cholesterol lowering effect is found when nuts replace saturated fat than when olive oil or carbohydrates are replaced. This finding has important clinical and public health applications'.
